The London Zoo has three of the cutest little residents you'll ever see.

Three Sumatran Tiger cubs, the world's rarest tigers, were born on February 3rd this year to momma cat Melati.

Now the tigress is inside a "cubbing den" with her babies, lounging around, nursing and kissing her babies.

One of the zookeepers said:

"We couldn't be more delighted with our new arrivals, and with how Melati is responding to her three cubs. We've been observing them 24/7, and one of us is always on duty to keep an eye on the little ones throughout the night. We've even been able to observe key milestones like their eyes opening and their tentative first steps."
